About AsterScan
The first independent block explorer for Aster Chain.
AsterScan is a free, public-good block explorer for the Aster Chain L1. It streams blocks and transactions in real time, decodes every action type, surfaces validator profiles, tracks whale activity, and ships a staking rewards calculator that reproduces the canonical AsterDEX formula.
We are not operated by the Aster team. AsterScan is independent infrastructure built and maintained by Kairos Lab, a security-research collective. All data is read live from public AsterDEX endpoints and the Aster Chain WebSocket stream — see /learn for the methodology.
Why we built it
Aster Chain launched in March 2026 with no first-party block explorer. Power users had to read raw JSON from the AsterDEX API or speculate from on-chain dashboards. AsterScan fills that gap — same data, surfaced as a navigable explorer that regular humans can use.
What's public on Aster Chain — and what isn't
Aster Chain is fundamentally an on-chain perpetual DEX, and the team made a deliberate trade-off: parts of every transaction are private by default. Specifically, when a user enables privacy mode, the order payload (symbol, side, price, quantity) is encrypted on-chain. The matching engine holds the key — outside observers (us included) see only that "an order was placed" without knowing what asset, what direction, or what size.
This is by design and protects users from front-running, copy-trading bots and competitor surveillance. It also means an explorer like AsterScan cannot show what it doesn't have — and we don't pretend to. When a payload is encrypted you'll see cipher: … on the transaction page. The privacy adoption tracker tells you what fraction of network traffic uses it at any given time.
What we do surface — for every transaction, private or not:
- Block height + timestamp
- Validator that sealed it
- Action type (PlaceOrder, CancelOrder, Deposit, etc.)
- Submitter address
- Gas fee
- And, for non-private txs, the full decoded payload
The Aster team is also active about expanding what they expose publicly — new endpoints ship with chain upgrades, and we wire AsterScan to surface them as soon as they're available. If a piece of data is missing from this explorer, it's either private by design or not yet exposed by upstream. We never invent or extrapolate.
What you can do here
- Browse every block produced on Aster Chain since launch.
- Search any transaction by hash and read the decoded action.
- Inspect any validator (operator type, commission, blocks produced).
- Run the staking rewards calculator for any lock period (26 weeks to 4 years).
- Track whale activity and large positions in real time.
- Hit the public read API (proxy to AsterDEX, free, no auth).
Funding & sustainability
AsterScan is funded by Kairos Lab. The explorer itself is free — no account gate, no paywall, no API key required. We have two monetization streams, both clearly labeled wherever they appear:
- An AsterDEX referral code on outbound "Trade on AsterDEX" links (we earn a fee share when users sign up via that link).
- Sponsored placements on the Ecosystem directory — paid promotional slots, always tagged SPONSORED. See the editorial policy below for the rules.
Editorial policy
AsterScan separates editorial content (curated, free, merit-based) from paid placements (sponsored, clearly labeled). We never blur the two.
What is editorial
Everything on this site that is not tagged SPONSORED is editorial. That includes every category and entry under /ecosystem (Trading, Yield, Validators, Bridges, Wallets, Tools, Documentation, Community), every page in /learn, and every metric / chart / list elsewhere on the site. Selection is on merit — we list apps and channels we believe are genuinely useful to Aster Chain users. Inclusion is never bought.
Want to be listed editorially? DM @aster_scan with name, URL, category, and a one-line description. We review based on: (1) the app actually ships on Aster Chain, (2) it has a public URL with a working integration, (3) it adds genuine value to users (not pure shill). No payment requested or accepted for editorial inclusion.
What is sponsored
Sponsored placements are paid promotional slots — clearly identified by a SPONSORED badge, and visually distinguished (gradient backgrounds, accent borders, rotating carousel above the editorial directory).
Sponsored slots are sold directly by AsterScan. They are never:
- Mixed in with the editorial directory below.
- Allowed to influence the editorial selection or ordering.
- Granted any verification badge they didn't earn separately.
- Sold to projects we believe are scams, honeypots, or operating in bad faith. We pre-screen every sponsor.
Conflicts of interest
AsterScan is built by Kairos Lab, which also runs other projects in the Aster ecosystem (e.g. AsterValidators). When we list our own projects in the editorial directory, we don't mark them sponsored — but we don't hide the affiliation either. The card description states "Built by Kairos Lab" or "AsterScan team" explicitly.
Corrections & removals
If you spot something inaccurate (wrong description, broken link, outdated metric), DM @aster_scan — corrections ship same-day. If you're a project listed editorially and want to be removed, we will honor the request without questions, within 48h.
Security
As a security-research shop, we care about being attacked correctly. AsterScan ships an active-defense layer (Nemesis): scanner probes get fed plausible fake credentials with monitored canary tokens, traffic is fingerprinted, and repeat offenders are tarpitted at the edge. If you're scanning us, we probably already know.
